LOS ANGELES - Brittany Murphy, the actress who got her start in the sleeper hit "Clueless" and rose to stardom in "8 Mile" before her movie roles declined in recent years, died Sunday in Los Angeles of what appeared to be natural causes, a Los Angeles County coroner's official said. She was 32.

Murphy was transported to the hospital after the Los Angeles Fire Department responded to a call at 8 a.m. at the home she shared with her husband, British screenwriter Simon Monjack, in the Hollywood Hills.

Assistant Chief Coroner Ed Winter said Murphy apparently collapsed in the bathroom, and authorities were looking into her medical history.

An official cause of death may not be determined for some time, since toxicology tests will be required, but "it appears to be natural," Winter said. He said an autopsy was planned for Monday or Tuesday.

Winter said Murphy's family was cooperating with the coroner's investigation. Funeral arrangements have not been announced, he said.

Los Angeles police have opened an investigation into Murphy's death, Officer Norma Eisenman said. Detectives and coroner's officials were at Murphy and Monjack's home Sunday afternoon but did not talk to reporters. Paparazzi were camped outside the multistory home, located above the Sunset Strip.

Messages left for Murphy's manager and agent by The Associated Press were not immediately returned.

Neighbor Clare Staples said she saw firefighters working to resuscitate the actress Sunday morning. She said Murphy was on a stretcher and "looked as though she was dead at the scene."

Murphy's husband, wearing pajama bottoms and no shoes, appeared "dazed" as firefighters tried to save her, Staples said. "It's just tragic," she added.

TMZ.com first reported Murphy's death Sunday morning.

Murphy's father, Angelo Bertolotti, said he learned of her death from his son, the actress's brother, and was stunned.

"She was just an absolute doll since she was born," Bertolotti said from his Branford, F
